There is no certainty in trading. This is the Dec14/feb15 fcpo spread. One of the locals last month commented "Just average the long spread position, no such thing as cut loss one la straddle trading"

Well, anything can happen in trading.  When the spread went to 120 most were scrambling to cut their losses,  hence the signal for the price to rebound...

Oh and after the carnage, a veteran trader remarked "In my 25 years of trading fcpo, I have never seen such a market, especially the straddle". It's 'spread' not 'straddle' by the way...
